these altecs look nice, they have what many mutlimedia speakers have - midrange drive.
If you are serious about critical music listening get a pair of good bookshelves, or even near field studio monitors.
For games I'd say Logitech, Z5500 or Creative gigaworks have the best oomph. Logitechs have both digital and anlog interface which might mater for you. I do not overestimate digital myself, not for this type of audio, but people like to have it, even though it may have no impact on sound... Altecs might be a nice compromise, but I have not auditioned them.
Razer = hype. Not worth it IMO. Proprietary connectors make it even more no-go. Or is it for the kicks and the green flashing logo? Then go for it
